SPECIFICATION forming pm of Letters Patent No. 630,129, dated August 41,1899.

Application filed Decenber 27, 1898. Serial No. 700,351.

To tZZ whom, t may concern:

Beit known that I, CHRISTIAN J. STRAvLo, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Sample-Cases, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to that class of sam ple cases shown and describedin Letters Patent granted to me August 25, 1896, No. 566,484.

The present invention relates to a construction comprising extensibleframes in which the sample-trays are pivotally mounted and by means ofwhich construction the trays may be compactly nested into assembledposition, so as to utilize the entire space Within the outercovers ofthe case 5 also, to provide an arrangement Whereby trays containinggreater space may be utilized and which when disassembled leave theirsurfaces unobstructed to provide for observation of the entire series oftrays.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a top View of the case in open position. Fig. II is an edgeview of one of the tray-carrying frames of the pair at one side of thecase. Fig. III is a similar View to Fig. II of one of the tray-carryingframes of the pair at the opposite side of the case from that' to whichthe frame shown in Fig. II belongs. Fig. IV is a side elevation of thecase in open position with the outer covers shown in crossseetion andalso showing the trays and their carrying-frames in dotted lines nested.Fig. V is aside elevation showing the outer covers in cross-section andthe trays and their carrying-frames in the positions assumed when thetwo sections are being brought together to nest the trays in foldedcondition. Fig. VI is a cross-sectional view through one of thetray-carryin g frames,taken on line VI VI, Fig. V7 and showing a portionof one end of one of the trays in top view. Fig. VII is an enlarged edgeview of a portion of one of the tray-earrying frames. Fig. VIII is anenlarged side View of a portion of one of the tray-carrying frames,illustrating the manner (No model.)

in Which the links to which the trays are piv oted are connected to thebars of the frame.

l and 1a designate the outer covers of the case, suitably hinged to abase 2. Rigidly seated on the base is a tray 3, having end Walls 4, thatare preferably metal bound to insure strength.

A and B designate the pivotal tray-carrying frames, connected to thestationary tray 3, the said frames being in pairs and arranged toswing-in counter directions from a central vertical position.

The frames A and B are extensible and contractible, so that their extentmay be increased or diminished. The frames A are shown in detail in Fig.Il and the frames B are shown in detail in Fig. III. Pivotally mountedin the frames A are trays 5, and pivoted in the frames B are trays Thetrays 5 are provided With pivot-ears 5, that receive pivot pins orscrews 5b, and the trays 6 are provided with pivot ears 6, that receivepivot pins or screws 6*.

The frames A are each constructed with an inner bar 7, pivoted to thestationary tray at opposite ends'of the tray 3 and provided withundercut grooves S. l

9 are extension-bars bearing tongues 10, that lit and operate in thegrooves 8 (see Fig. VI) in the sliding movement of the extensionbars.rlhe extension-bars are adapted to be drawn outwardly into the positionsshown in Figs. Ifto V, inclusive, or contracted into the `position shownin dotted lines, Fig. IV. On

the extension-bars are legs l1, adapted to rest `on the edges of ltheouter cover l when the frame A is extended. The inner bars 7 areprovided with longitudinal slots 7 f. The extension-bars 9 are providedwith longitudinal slots El"L and 9b.`

12 designates slides having longitudinal slots 13 and provided with ears14,that receive pivot-pins 5b, which seat in ears 5a of the adjacenttray 5 to support said tray.` The with the length of the slots andmaypass 'therethrough in attaching the slides to the bars or indetaching them. The form of these pins is `shown most clearly in Figs.VI and VIII, and a number of them are used throughout the frames, whichwill be referred to by like designation. The movement of the slides 12in outward direction is limited by stops 7b on the faces of the bars 7.

16 designates slides connected to the slides 12 by pivot-pins 15,passing through the inner ends of said slides 16 and through the slots13 of the slides 12 and also through the slots 7a of the bars 7. Theslides 16 are provided with ears 17, that receive tray-supportingpivot-pins 5b, and each slide 16 is provided with a longitudinal slot18. The outer ends of the slides 16 contain slide-pins 15, seated in theslots 9L of the extension-bars 9. The slide-pins 15 in the outer ends ofthe slides 16 also pass through slotted slides 19, located at the innerfaces of the extensionbars 9. The slides 19 are provided with ears 20,that receive tray-supporting pivot-pins 5b.

21 designates slides having pivot-pin-receiving ears 22, these slides 21being connected to the slides 19 by slotted links 2l, that connect withthe slides 19 and 21 by slide-pins 15. The outer ends of the slides 21are provided with slide-pins 15, that fit and operate in the slots 9b,located near the outer ends ofthe extension-bars 9. The tray 5, mountedat the outermost ends of the extension-bars 9', is pivotally mounted onpivot pins or screws 5b, that are seated in ears 23, rigid with theextension-bars 9, so that the outermost tray 5 (which is the topmosttray ,when the trays ot' both sections are nested together) is onlymovable in' connection with thel extension-bars.

Referring now to the opposite side of the case equipped with thetray-carrying frames B, the 'frames B are composed of inner bars 24 andextension-'bars 26, similar to those 7 and 9 of the frames A. The inner-bars 24 are provided with longitudinal grooves 25, and theextension-bars 26 are provided with tongues similar to those 8 thatoperate in said groovejs 25. The inner bars 24 are provided Withlongitudinal slots 24, and the extension-bars 26 are provided withlongitudinal slots 26a and 2Gb, the slots 26b extending to approximatelythe ends of the extensionbars.

`27 designates slotted slides movably connected to the inner bars 24 bypivot-pins 15,

, extending through the slots 24, contained by said inner bars. Eachslide 27 is provided with an ear 28, that receives pivot pins or screws6b, that enter the ears 6a, carried by the trays 6. The outward movementof the slides 27 is limited by stops 24b on the faces of the inner bars24.

- and passing through the slots in the slides 27 and through the slotsin the bars 24. The

slides 29 are provided with ears 30, that reA ceive tray-supportingpivot-pins 6b. The outer ends of the slides 29 contain slide-pins 15,that pass through the inner ends of slotted slides 31 and also throughthe slots 26'n in the extension-bars 26 to the exterior thereof. Theslides 31 are provided with pivot= pin-receiving ears 32 and areconnected by slotted links 33 to slides 34, provided withpivot-pin-receiving ears 35, which slides 34 are connected by slide-pins15 to slides 36, having pivot-pin-receiving ears 37. The two outermostslide-pins 15, which pass through the slides 36, are located in theslots 26, so that the outermost tray 6 is capable of being movedinwardly from the extreme outer ends of the extension-bars 26, therebyleaving a space between the outer ends of said extension-bars when thetrays are in nested or folded condition, into which space the outermosttray 5 at the opposite side of the case is received on the assembling ofthe trays into the nested condition shown by dotted lines, Fig. IV. Theframes B are provided with legs 11a, carried by the extension-bars 26,similar to those 11, carried by the frame A, which are adapted to reston the cover 1 when the frame B is extended.

A portion of the slide-pins 15 in each of the frames A and B are looselyseated in the slides which they connect, so that they may be turned tobring their elongated heads into line with the length of the slots inthe frame-bars to be capablevof passing therethrough without removingthem from their connections. This arrangement is provided for thepurpose of permitting the disconnection of the slides from theframe-bars in the event of any of the links becoming broken. In Fig.VIII, I have illustrated the manner in which such disconnection isaccomplished. When the slide-pin shown is removed from the bar'-contained slot in said igure, it will be seen that the opposite ends ofthe connected slides may be brought toward each other., and theslide-pins at said opposite'ends will be turned to bring their elongatedheads into line with the slots in t-he frame-bars to pass therethrough.

In assembling the trays into nested condition each section is movedupwardly and inwardly from the extended positions shown in Figs. I andIV into the positions shown in Fig. V while the frames A and B are stillextended, in which condition it will be seen that the trays of theopposing sections are odset -from those of the other section, so thatthe alternate trays of the sections may enter above or below traysopposing them. The frames being brought together, the trays 5 and 6 liein a tier, but `separated by spaces between them above and below eachtray. The extension-bars 9 and 26 are then pressed downward to contractthe frames A and B,

causing the slides throughout said framesto A be moved inwardly and thetrays carried by said slides to be lowered into compact condition, eachsucceeding tray descending onto the one beneath it. The lowermost tray 6rests on the stationary tray 3 and the topmost tray 5 moves down ontothe topmost tray 6, and therefore is the topmost tray of the tier whenthe sections are nested.

I claim as my invention- 1. In a sample-case, the combination of anouter case, two pairs of extensible frames hinged to said outer case,movable slides carried by said frames, and trays pivotally mounted insaid slide; substantially as described.

2. In a sample-case, the combination of an outercase, comprising a baseand covers hinged to said base; two pairs of extensible frames hinged tosaid outer case, movable slides carried by said frames, and trayspivotally mounted in said slides; substantially asv described.

3. In a sample-case, the combination of an outer case, comprising a baseand covers hinged to said base; a stationary tray carried by said base,two pairs of extensible frames hinged to said stationary tra ys,movableslides carried by said frames, said slides being con nected to eachother and the said frames, whereby movement imparted to said frames maybe communicated to said slides to move them in unison with the frames,and trays pivotally mounted in said slides; substantially y
